I was trying to track some Allegiant aircraft, using the tail number, none of Allegiant's Aircraft show up. Every time I type in an AYY tail number I always get the "FlightAware couldn't find flight tracking data for..." Why is this? Thanks in advance.

Do you have an updated list of what airlines do participate and provide tail numbers on flightaware? And why would a big one like Southwest not do it - they provide tail numbers on the BTS website since they handle more than 1% of airline revenue.

Southwest: Because they are required by law to give the data to the BTS and are NOT required by law to give the data to FlightAware.

The system doesn't seem to be working correctly for US Airways. Why is this?

Example, type in the Allegheny retro reg.....N745VJThis plane was in TPA on Saturday April 7 and again on Monday April 9, overnighting until Tuesday morning. But that information doesn't show. I can rarely find an aircraft en route and I don't think their 734 show up at all.
